North American Steel Frame Home Insulation Choice: Yellow Frame Fiberglass Batt/Pre-cut Roll for Efficiency and Energy-saving

Yellow frame fiberglass batt by Unitedinsulation is manufactured exclusively for North American steel-framed construction. The material made of long fibers and bonded with thermosetting resin is characterized by light weight and good flexibility. In addition to its availability in various widths (e.g., 16" [406mm], 24" [609mm]), thickness (3.5" [90mm] to 9.5" [240mm]) and length (48" [1219mm]/96" [2438mm]), yellow frame fiberglass batt provides the best fit for insulation of the inner walls, roofs, and outer walls in the steel-frame North American houses.

When this product was applied to the insulation of both steel keel walls and roof in a mixed residential and industrial project in the Midwest, there was a dramatic increase in the stability of indoor temperature and significant reduction in energy consumption as well as outstanding winter and summer insulation. In terms of insulation effectiveness, the product has an R-value (ASTM C518) ranging between R11 and R30. It has good fire-resistant properties (flame spread index ≤25 and smoke development index ≤50 per ASTM E84 / UL 723 standards). In addition, it has good sound insulation properties.

Moreover, the product can be pre-coated with FSK, Vinyl, Foil, WMP, and Kraft topcoating as per customer preference and has very good vapor barrier property. Compressed packing also helps to reduce shipping and storage cost for customers in North America.
